Is it possible to train a neural network to learn something via video footage?
Short answer: No.

Long answer: A neural network is a function that maps input data (e.g. a picture) to output data (e.g. probability that the picture contains a dog). What you propose does not seem like the sort of task this tool is suited for, though I'm not willing to claim that it can't be done.

If you are interested in computer-generated artwork, I encourage you to learn about Generative Adversarial Networks and style transfer.
